Based on the results of the comparison, a notification action is taken.

FIELD

The present disclosure relates generally to wireless data communications, and more particularly, to a contextual push notification service.

BACKGROUND

Several options are open to an enterprise that may want to reach a potential audience with news of events that may be interesting, such as for example, a sale or a meeting notice. Some popular options include email, text message (SMS), or an ad within a web browser window. Such notifications are server-based broadcasts. Some, such as those delivered within a web browser window, rely on being discovered by chance by the potential audience. Consequently, some in the potential audience may be overburdened by repeated or unwanted notifications, while others may not want to receive notifications at all. The popularity of mobile devices, such as smart phones and tablets, is increasingly influencing the way content generators, such as a business advertiser or other enterprise, reach out to potential consumers of their content. For example, an advertiser may publish its content for all potential platforms in an attempt to capture as much of the potential audience as possible. Additionally, the advertiser may increase how frequently the advertisement is modified so that it becomes more appealing to the potential audience. This flexibility in generating the content may enable an advertiser to reach a larger audience in a more timely manner, and at a more cost effective price point in comparison to more traditional methods, such as print. On the other hand, a mobile device user may be interested in receiving some content, but may easily become overwhelmed and irritated by its frequency and volume. Where a balance between the interests of an advertiser and a consumer may be reached, both may benefit.

BRIEF SUMMARY

Among other things, a contextual push notification service is provided. According to an embodiment of the invention, a contextual push notification service comprises: receiving, by a mobile device, a notification message comprising at least one context rule; and a notification message. The received at least one context rule is compared, at the mobile device, with at least one user context preference. A notification action is taken, at the mobile device, based on the comparing of the received at least one context rule with the at least one user context preference.

DETAILED DESCRIPTION

Embodiments of the present invention will now be described with reference to the figures. Referring to FIGS. 1-2, a contextual push notification service system 100 and method 200 provide an exemplary implementation for a contextual push notification service.

FIG. 1 is a block diagram of an exemplary embodiment of a system 100 for a contextual push notification service. The system 100 consists of at least the enterprise push environment 140 and the mobile environment 120. The push service environment 130 may be incorporated within the enterprise push environment 140, where the enterprise performs both the functions of authoring notification messages and managing the formatting and delivery of the notification messages to the target mobile devices 127 on the various subscriber networks. The enterprise push environment 140 includes a push notification authoring 148 environment from which a developer may compose push notification messages. The push notification authoring 148 environment may be a workstation or another input device configured with software development tools suitable for authoring push notifications, such as JavaPNS, PHP, and JSON.

The enterprise push environment 140 also includes an enterprise context rules authoring environment 149, where the developer may create a set of context rules that may further segment the subscribers in an application's provisioning profile by one or more criteria. The list of subscribers who have installed an application and have registered to receive messages from the application may be referred to as the application's provisioning profile. The push environment administration 147 may be a workstation configured for the administration and operation of the enterprise push environment 140, such as performance monitoring, software updates, and user management. The push notification analytics 145 environment may be configured to receive feedback results including a count of notification messages that were sent, along with a count of how many notifications that subscribers chose to receive, or to ignore. By applying statistical and other analytics, the efficiency of notification messages may be measured and improved. The enterprise push environment 140 may also include notification storage 138 where application provisioning profiles, subscriber lists, notification message templates, and analytical data may be stored. The notification storage 138 may be a persistent storage device. Although shown as a single unit, the notification storage 138 may be a combination of fixed and/or removable storage devices, such as fixed disc drives, Storage Area Network (SAN), solid state drives, floppy disc drives, tape drives, removable memory cards or optical storage. The functions of the various components in the enterprise push notification environment 140 may be performed by multiple software modules within a computer, or multiple dedicated computers. Where the enterprise push notification environment 140 is implemented in multiple software modules, 190 represents a bus over which communication among the software modules takes place. The multiple software modules share the host computer resources, such as the processor(s) 191, memory 192, and notification storage 138.

Where the enterprise push notification environment 140 is implemented in multiple dedicated computers, 190 represents a network over which the computers communicate. In that embodiment, the processor(s) 191, memory 192, and notification storage 138 are illustrative of these components as they are installed in each of the dedicated computers. In either embodiment, computers participating in the enterprise push notification environment 140 are under the control of an operating system (not shown). Enterprise context rules and notifications 110 are output from the enterprise push notification environment 140 and transmitted to the push service environment 130 through a well-known network, such as LAN, WAN, or internet.

The push service environment 130 includes push service administration 139, which may be a workstation configured for the administration and operation of the push service environment 130, such as performance monitoring, software updates, and user management. The push service analytics 135 environment may be configured to receive feedback results from the mobile environment 120, including a count of notification messages that were sent, along with a count of how many notifications that subscribers chose to receive or to ignore. These feedback results may be transmitted back to the enterprise push environment 140 over a well-known network (not shown) for processing, for example, by the push notification analytics 145 environment. The push service environment 130 also includes at least one push mediator 137, which is a client interface between the push service environment 130 and the corresponding subscriber network, such as Apple Push Notification Service® (APNS). The push service storage 136 provides storage, for example, for application provisioning profiles, subscriber lists, pending notification messages and their delivery schedules, and analytical data. The push service storage 136 may be a persistent storage device, a combination of fixed and/or removable storage devices, such as fixed disc drives, Storage Area Network (SAN), solid state drives, floppy disc drives, tape drives, removable memory cards or optical storage. As in the enterprise push environment 140, the functions of the various components in the push service environment 130 may be performed by multiple software modules within a computer, communicating with each other over a bus 190 and exploiting the processor(s) 191, memory 192, and push service storage 136 of the host computer. Where the push service environment 140 is implemented in multiple dedicated computers, 190 represents a network over which the computers communicate. In that embodiment, each dedicated computer includes the processor(s) 191, which is representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, and the like, and one or more memory modules 192. Notification messages and context rules 120 formatted for the protocol of a particular subscriber network are transmitted via well-known network to the mobile push server(s) 125 in the mobile environment 120.

The mobile environment 120 includes the mobile push server 125 corresponding to a subscriber network, such as the APNS. The mobile push server 125 transmits the notification messages and context rules 126 via satellite over its subscriber cell service network to one or more target mobile devices 127. A mobile device comprises a smart phone, tablet computer, and personal digital assistant (PDA). In general, a mobile device is a device that is configured to run a mobile application (mobile app). The target mobile device 127 contains a notification agent 128, which may be implemented for example, as a software agent, firmware and a device driver. The target mobile device 127 also stores user context preferences 129, which the subscriber may input and modify for each installed application, and which may be applied to each received notification message.

The particular description in FIG. 1 is for illustrative purposes only; it should be understood that the invention is not limited to specific described embodiments, and any combination is contemplated to implement and practice the invention.

Referring now to FIG. 2, an exemplary embodiment 200 of a contextual push notification service is illustrated. A push notification is a technique that may be used by an application owner, such as a business enterprise, to alert a mobile device user who has subscribed to the application that information is waiting to be viewed. Exemplary information may include a message, a calendar event, or data such as an update to the app. At 210 a developer, i.e., author, may compose a push notification message using a workstation or a push notification authoring environment 148 (FIG. 1), or another input device configured with software development tools suitable for authoring push notifications. Such exemplary development tools include, JavaPNS, PHP, and JSON. In addition to the push notification message, the developer, using an authoring environment such as 149 (FIG. 1), authors a set of context rules that may further segment the subscribers in an application's provisioning profile by one or more criteria. In general, a context rule captures a contextual condition under which a notification may become meaningful to the developer or to the subscriber. When referred to in the context of the developer, a context rule describes a condition that makes the delivery of the notification message meaningful to the developer. For example, a business enterprise may specify that a notification message that announces a sale should be sent to subscribers on a certain day, or when a subscriber is physically near the retail store. Context rules can go beyond location as a context, for example, pertaining to a locomotive state (walking/sitting/loitering) of the user. However, a subscriber may also define one or more context rules, in this case to describe, for example, times when the subscriber should not be interrupted by notification messages. The subscriber's context rules may also be referred to as local context rules, user context rules, or user context preferences.

After the notification developer composes them, the notification message and the associated context rules may be forwarded to an intermediary service, such as the push service environment 130 (FIG. 1). The push service environment 130 (FIG. 1) contains one or more agents, referred to as push mediators 137 (FIG. 1), each one corresponding to the protocol of a target server, such as Apple Push Notification Service® (APNS) and Google Cloud Messaging for Android® (GCM). Since the push service provides a push mediator for each target, in-depth knowledge of each target server's protocol by the notification developer is not needed to properly author and format a version of the notification message for each target.

The push service may, on behalf of the developer, manage subscriber lists, notification message storage, and the scheduling and delivery of the notification message according to its associated context rules. Additional services may include gathering and sending the results of one or more notification messages to the developer. Such results may include a count of notification messages that were sent, along with a count of how many notifications the subscribers chose to receive, or to ignore.

In another embodiment, the developer may forward the notification message and the associated context rules directly to the server of one or more providers. However, specialized knowledge of each target server's protocol would be needed to properly author and format a version of the notification message for each target, increasing the potential for errors.

At 215, the push service uses a communication protocol, such as for example Hypertext Transfer Protocol (HTTP) or Transmission Control Protocol (TCP) to forward the notification message and associated context rules to the mobile push server 125 (FIG. 1) of one or more subscriber networks, such as Apple Push Notification Service® (APNS) and Google Cloud Messaging for Android® (GCM). HTTP is a well-known stateless application-layer protocol for communicating between distributed systems, particularly web-based hosts and clients. TCP is a well-known communications protocol that provides reliable, ordered, delivery of data over a network.

At 220, the mobile push server 125 (FIG. 1) in the mobile environment 120 (FIG. 1) dispatches the notification message to the target mobile devices 127 (FIG. 1) that were specified by the notification developer. A mobile device become eligible as a target when a mobile subscriber installs and registers an application, resulting in the mobile device being added to the application's provisioning profile. Since the push service maintains multiple push mediators 137 (FIG. 1), the notification message and context rules may be dispatched to more than one subscriber network according to the notification developer's desired delivery schedule.

300 (FIG. 3) depicts a detail representation of the notification agent that is shown generally as the notification agent 128 in FIG. 1. References to the notification agent in the following discussion will be made using notification agent 300 (FIG. 3). At 225 the notification message is received at the target mobile device 127 (FIG. 1) by a notification agent 300 (FIG. 3) that is installed on the target mobile device 127 (FIG. 1). The notification process 305 (FIG. 3) may evaluate the received notification message to determine which of the context rules that are associated with the message should receive further analysis for comparison against the real-time contextual condition, or context, of the target mobile device 127 (FIG. 1). In another embodiment, the notification process 305 (FIG. 3) may query the push service server to retrieve the associated context rules. However the context rules are obtained, the notification process 305 (FIG. 3) examines the context rules to determine what types of data should be gathered by the target mobile device's sensors 335 (FIG. 3). The gathered sensor data may be input to the context evaluator 320 (FIG. 3) to computationally determine the real-time contextual condition of the target mobile device 127 (FIG. 1). The notification process 305 (FIG. 3) also retrieves the user's context rules from local storage on the target mobile device 127 (FIG. 1), such as for example, the notification repository 310 (FIG. 3).

A context rule may be defined over multiple sensors 335 (FIG. 3) on the target mobile device 127 (FIG. 1), for example a GPS location in combination with a proximity to a WiFi access point. Based on the results of analyzing the context rules, at 235 the notification process 305 (FIG. 3) communicates with the sensing planner 315 (FIG. 3) to request that the sensor controller 330 (FIG. 3) activate and poll one or more sensors 335 (FIG. 3) on the target mobile device 127 (FIG. 1). A duration to gather the sensor data may also be communicated from the sensing planner 315 (FIG. 3) through the sensing controller 330 (FIG. 3) to each activated sensor 335 (FIG. 3). A different duration may be communicated to each activated sensor 335 (FIG. 3). The sensor data that is collected through the sensor controller 330 (FIG. 3) may be gathered in one or more buffers 325 (FIG. 3) pending further processing in the context evaluator 320 (FIG. 3). Computations may be performed on the gathered sensor data to determine whether the contextual condition of the target mobile device 127 (FIG. 1) satisfies a context rule that was associated with the notification message. A contextual condition may be represented as a mathematical expression that evaluates inputted sensor data to determine whether the sensor data equates to a known attribute. An attribute may be raw data or a function within the notification agent 300 (FIG. 3) and stored locally, for example in the notification repository 310 (FIG. 3). For example, an attribute may include a function that receives data from an accelerometer sensor and, based upon calculations, evaluates that the data resolves to the action of walking.

At 240, the context preferences that the target mobile device user defined and stored on the target mobile device 127 (FIG. 1) are extracted, for example, from the notification repository 310 (FIG. 3), and passed to the context evaluator 320 (FIG. 3). These context preferences may be referred to as local context rules, user context rules, or user context preferences. For example, a user may define a user context preference that between certain times of the day, notification messages should not be presented to the user. Similarly, if the user is in a certain shopping center, present notification messages, such as coupons, from any store in the shopping center. The user may also set a preference for how many times to replay a notification message before expiring it. Other user context preferences include social status (i.e., with friends, with family, alone), current activity (i.e., walking, jogging, in a meeting), and the time of day.

At 245, following computations on the gathered sensor data, the context evaluator 320 (FIG. 3) further compares the context rules that match the contextual condition (i.e., successful context rules) against the user context preferences. Note that the comparison of the context rules with the contextual condition is performed on the mobile device, rather than requiring that the user's context be transmitted to the server for the comparison to take place there. This not only contributes to protecting the user's privacy, but also tends to reduce the computational demand at the server.

When at 250 a user context preference matches a successful context rule, at 260 the notification message is prepared, or rendered, for presentation to the user. Rendering information may be contained in the associated context rule of the notification message, and may include a number of times to replay a message and an expiry date, for example. At 265, the prepared notification message is presented for the user to view. However, if at 250, a user context preference does not match a successful context rule, at 255 the removal from the target mobile device 127 (FIG. 1), or expiry, of the notification message is handled. For example, if the successful context rule does not match a user context preference, but has a date range, the notification message may be retained on the target mobile device 127 for the duration of the date range rather than deleted, even though the user context preference is not satisfied on this day. The context evaluator 320 (FIG. 3) may re-evaluate the user context preference against the contextual condition each day during the date range until the date range is exhausted.

In operation, for example, a department store may create a notification message for a promotional sale. The notification message should be presented to the user on the target mobile device 127 (FIG. 1) for a consecutive number of days when the conditional context of the target mobile device 127 (FIG. 1) indicates proximity to the department store. After the number of days has elapsed, the notification message should be deleted from the target mobile device 127 (FIG. 1). In this example, whether the user sees the notification message depends on whether the user satisfies the proximity context rule. Although the user may see the notification message every day, some days, or not at all, the department store only needs to create and dispatch the notification message once, accompanied by appropriate context rules.

Referring now to FIG. 4, computing device 400 may include respective sets of internal components 800 and external components 900 that together may provide an environment for a software application, such as a Push Notification Service (FIG. 1).
